Specification of Letters Patent. Patgnted $11111 14, 131%}, Application filed Qctober 8, 1909.

Serial No. 521,765.

To all whom it may concern..-

Be it known that I, llnxnr G. Vonnrr, a

citizen of the United States, residing at New Britain, coiinty of Hartford, State of Connecticut, have invented certain new and use ful Improvements in Panic-Bolts with Adjustments Between 'lloggles and Bolts, of which the following is a full, clear, and

My invention relates to improvements in locks for doors and is particularly concerned with improvements in looks ofthe so-called panic bolt type, which are intended for use on doors of public buildings and the likein Which large numbers of persons congregate and is designed as an improvement upon the constructions illustrated in my Patent No. 912,211, granted Feb. 9, 1909, and copending application No. JA'LOM, filed'Aug. 5, 1908. These locks are provided with means such as a .bar extending transversely of the door at approximately the height of the usual lock and connected with the bolt operating mechanism whereby the bolt will be released by pressure against such bar.

The object of my invention is to provide description with means for adjustment between the lock bolts and the operating mechanism whereby said bolts may be at all times positioned accurately and properly with respect to their striker plates to compensate for wearon the striker plates and for variation in the relative position of the striker plate and bolt due to settling of the door or. otherwise.

A further object is to simplify the lock mechanism proper by which" the bolts are operated and to provide a substantially equal and uniform support of the transverse operating bar in operative position throughout its length.

'lVith these objects in view the invention consists in the construction and arrangementof parts a preferred embodiment of which is illustrated in the accompanying drawings,

in which,

Figure 1 is a face view of the inner side embodying my invention attached thereto. F ig; 2- is a rear view of'the interior of the lock case, the cap platt 'bcing removed, showing the locking mechanism in the position assumed when the same is locked. Fig. 3 is a view similar to Fig. 2, showing the mechanism in un with the case in section of the locking mechanism showing the operating lever therefor. Fig. is a view similar to Fig. 4 of the supporting bracket for the outer end of the operating bar. Fig. 6 is a rear view of one of the bolt housings, showing the bolt mounted thereon, and Fig. 6* shows a detail ofone of the bolts.

In the embodiment of my inventionherein selected for illustration, 1 indicates the door to which the lock is attached.

2 indicates the lock case containing the bolt operating mechanism proper.

3-3 indicate bolt operating rods connected with the lock mechanism in the case 2 and arranged to operate the bolts t-4 respectively in the housin s 5 5 which are secured to the upper and ower ends of the door respectively.

6 indicates the operating bar extending transverse of the door and supported at one end by an actuating lever 7 operatively connected with the locking mechanism and at the opposite end by lever 8 mounted in the supporting bracket 9. at the opposite sideof '80 the door.

Referring to Figs. 2, 3 and 4:, the bolt operating mechanism proper comprises a slide 10 mounted between suitable guides 1n the lock case 2 and normally held in the po- 85 sition indicated in Fig. 2 by means of a spring 11, said slide being provided on its, forward side with a series of rack teeth 12, arranged to be engaged by a segmental rack 13 on the actuating lever 7. also provided upon one side with a second series of rack teeth 14:. arranged to mesh with a pinion 15 rotatably mounted on the lock case 2. Fixed to the pinion is a toggle lever 16, which is connected by means of tog- 95 gle links 17 and 17 with. the blocks 18 and 18 arranged to slide within the opposite ends of the lock case and to which the bolt actuating rods 3 and 3' are adjustably attached. The outer sponding cone-shaped sockets 19 in the inner ends of the bolts 4 and t. By this construction the actuating rods may be freely turned for adjustment. the inner ends of said rods 313 are threaded to engage corresponding threaded bores it) in the sliding blocks lSand 18 respectively,

Said slide is extremities of the actuatmg rods 3 and 3 are coned to fit corre- To effect such adjustment, 10 5 and each lad is provided with a lock nut 21 having an extended sleeve 22 which serves to conceal the threads on the rod 3 throughout a considerable range of adjusting movement 7 of said rods, and thereby preserve a smooth finish at these points oi connection.

The bolts 4 and Pat the top and bottom of the door respectively being of the same construction, a description of one will suffice for both.

Referring to Fig. 6, the housing 5 is provided with guides 23 and 24; in which the bolt slides, and said bolt is provided at the head 25 with a shoulder .26 which normally engages-the stop formed by the guideway 23 and the opposite end of the bolt is provided with a shoulder 2'7 between which and the guideway 23 is interposed a spring 28 which tends normally to retract the bolt within its housing. The bolt is prevented from rotation in its housing by a pin 29 engaging a slot 30 in the shank of the bolt.

Referring to Fig. 5, it will be seen that the actuating lever 8 which supports thebutbr end of the transverse operating bar 6 is pitividecl with an arm 31 connected by a spring 32 with the screw stud 33 in the interior of the bracltet 9, the action of said spring, together with that of the spring 11 in the lock case, tending to move the operating bar away from the door. The combined action of these springs 11 and 32 furthermore is suificient to project the bolts 4 and 4 against the pressure of their springs 30.

Referring to Fig. 6 it will be noticed that the head of the bolt is beveled at a considerable angle at 34 which beveled surface faces the outside of the door and engages the striker plate in such manner that upon outward pressure upon the doorthe striker" plate tends to retract the bolt. In the normal looking position of the mechanism, however, the pivotconnections of the links 17 and U with the toggle lever 16 and with the connecting blocks 18 and 18 arc substantially in vertical alinemcnt, as will be seen from Fig. 2, hence retraction of the bolts by outward pressure thereof on the striker plates willbe blocked until these pivotal connections are drawn out of alinement by rotation of the pinion 15 through the slide 10 and bar 6. The parts are so arranged, however, that upon very slight actuation thereof by the operating bar 6 further outward pressure on the door combined with the action of the bolt springs 30 will serve eli'ectually to retract the bolts and permit the door to freely open. The bolt heads furthermore are provided at the rear with beveled faces 35 which cooperate with the striker plate to facilitate the retraction of the bolts to permit the closing of the door.

. By the construction just described it will be seen that very slight movement of the transverse operating bar 6 toward the door will serve to break the toggle connection or the ,bolt springs 30 cooperate to completely retract the bolts. This mode of operation is 7( particularly advantageous in case or" panics, inasmuch as all tendency of the bolts to become jammed is practically eliminated.

While I have herein described a preferred embodiment of my invention, it is to be 5 understood that the same may be varied in detail and relative arrangement of parts without departing from the spirit or scope thereof.
